Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Understand the op-amp buffer configuration and calculate basic circuit impedance.

In this learning object you'll review direct, inverse, joint, quadratic, and combined variations.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

Students use algebra to rearrange formulas and solve for the missing volume, density, or mass quantity.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

Learners observe animations showing how data is converted between serial and parallel flow.

This game will give you practice with the computation skills you need for ratios, proportions, and measurement conversions.
